Leners Patent No. 95,555, daad om. 5, 1869.

.The Schedule referred to in these Letters Patent and .making'pada of the same.

vfication, wherein- Figure l is a plan of the joint-chair, support, and rail;

Figure 2 is a side view of the same parts; and

Figure 3 is a cross-section at the line x x, iig. 2.

Similar letters denote the sam'e parts.

Y The object of this invention is to sustain thel joint at the endsof the rail, by a slightly-yielding support, so that there will be less concussion at the ends of the bars from the passing wheels.

I accomplish this object by the use of a wroughtiron chair that grasps the ends of the rail and sits upon a plank that bridges the space between two crossties; thereby the ends of the rail are supported, but there is a ,slight yielding of theplank-bridge to the passing weight, so as to relieve the rails from concussion.

In the drawing, c a represent cross-ties, of usual character.v Upon these the bridge-plank b rests, and p sustains, near the middle. the joint-chair e.

This joint-chair e is made with lips, 2 2, that turn over and grasp the flanges of the rails f, and with flanges 33, turned downward at the sides of the bridgeplank l). l'

The edges of the bridge-plank?) are made with re-A cesses for receiving the flanges 3 3, so thatsaid flanges prevent thejoiut-chair e moving either laterally ou the plank b, or in any other direction.

The bridge-plank b is to be secured t'o the ties a by the spikes i, which 'may also hold the flanges of the.

rails j, as shown.

It will now be understood that the joint-chair grasps the rails, holding them firmly at their ends. 1t also connects with the bridge-plank, and said bridge-plank forms a slightly-yielding support Vtov the ends of the rails, preventing the concussion heretofore usual.

What I claim, and desire to secure by Letters Patent, is-

The joint-chair e, formed 'with the lips 2 2 and flanges 3 3, in combination with the bridge-plank l),

substantially as set forth.

In witness whereof, I have hereunto set lnysigna ture, this 25th day of June, A.D. 1869.
